Food can also be part of a ceremony. For example, many cultures have ceremonies to celebrate the birth f a child, and food can play a significant role. In china, when a baby is one month old, families name and welcome their child in a celebration that includes giving red-colored eggs to guests. In Afghanistan, parents feed babies butter and sugar for he first six days of life to symbolize cleansing. In a ceremony around 100 day after a child's birth, Japanese families symbolically 'feed' the baby by putting different kinds of food too its lips, and sometimes putting a single grain of rice in its mouth. This ritual expresses their hope that the baby will never be hungry. In many cultures, round foods such as grapes, pomegranates, bread, and moon cakes are eaten at welcome celebrations to symbolize family unity.
